SASI-I-PIVOT.

To all whom it may concern:

Be it known that we, FRED RAUSCH and JosnrH DAVIS, citizens of theUnited States, and residing at Chicago, in the county of Cook and Stateof Illinois, have invented a new and useful Improvement in Sash-Pivots,of which the following is a complete specification.

The main objects of this invention are to provide a sash pivot for adeck sash which will permit the sash to be quickly inserted in orremoved from the window frame; to provide a sash pivot in which thepivot pin is adapted to be moved in or out of operative position by apartial rotation of the pin; and to provide a sash pivot for deck sashwhich will afford a safe and positive support for the sash and entirelyeliminate the danger of the sash falling from-its bearings.

A specific construction embodying the invention is illustrated in theaccompanying drawings, in which:

Figure 1 is a fragmentary section of a sash provided with a pivotembodied in this invention, and shown in sideelevation. Fig. 2 is afragmentary view of the sash and showing the pivot in front elevation.Fig. 3 is a vertical section of the sash pivot with parts in elevation.Fig. 4 is a side elevation of the ratchet member and the barrel for thepivot pin. Fig. is a bottom plan view of the ratchet member and thebarrel for the pivot pin. Fig. 6 is a front elevation of the ratchetmember and the barrel for the pivot pin. Fig. 7 is a side elevation ofthe pivot pin. Fig. 8 is an end elevation of the pivot pin. Figs. 9 and10 are side elevations of the ratchet bolt. Fig. 11 is an end elevationof the ratchet bolt.

In the construction shown, a housing 1 is secured in a vertical positionto the windowpost 2 at the side of the window opening. A verticallymovable ratchet bolt 8 is contained in said housing and projects throughthe bottom thereof. A coiled spring 4: is carried on the bolt 3 andbears at one end against the top of the housing and at the other end itbears against a flange 5 on the bolt, which flange also contacts withthe bottom of the housing and limits the downward movement of the bolt.Said spring normally holds the bolt at the lower limit of its movement.

A quadrant ratchet 6 is provided with an Specification of Letterslatent.

attaching plate which is adapted to be attached to the sash 8 inposition for the toothed edge of the ratchet to engage the ratchet bolt3.

For the purpose of pivoting the sash in he window opening in positionfor. the ratchet to coact with the ratchet bolt 3, a plate or extension9 extends downwardly from the housing 1 and is provided with a bearingsocket 10. In the bottom of the plate is a guide groove 11 which extendsupwardly and inwardly from the back of the plate to the end of thesocket 10. Mounted upon the side of the ratchet 6 is a barrel 12 havingapertured ends in which is rotatably mounted a retractable orlongitudinally movable pivot pin 13, which, when in one position, isadapted to project from the end of the barrel and into the socket 10.For convenience of description that end of the barrel 12 which isadjacent to the ratchet is referred to as the inner end, and theopposite end of the barrel is referred to as the outer end.

The barrel is provided in its side with a cam slot 14 which extends fromthe bottom of the barrel upwardly and laterally toward the outer end ofthe barrel. Near the bottom of the slot and on the side thereof adjacentto the outer end of the barrel is a stop lug 15. The pivot pin 13 isprovided with a laterally directed handle 16 which is formed of springsteel and projects outwardly through the slot 14. hen the handle isat-the lower end 17 of the slot 1 1 the pivot pin projects from theinner end of the barrel into the socket 10. The outer end of the pin 13is provided with a head 18 which is adapted to abut against the outerend of the barrel and limit the movement of the pivot pin into thesocket. When the pin is at the inner limit of its movement in the socketthe handle 16 is beneath the stop lug 15 and cannot be raised above saidlug without sufiicient force being applied to the handle to cause thelug to spring the handle laterally. After the handle passes said lug,further movement of the handle toward the upper end of the slot acts toretract the pin from the socket.

The head 18 of the pivot pin is elongated and one end thereof is adaptedto engage behind a hook 19 on the outer end of the barrel when thehandle is at the lower limit of its movement. The hook affords anadditional resistance to retraction of the pin when the latter isextended into the socket. On the outer end of the barrel 12, above thehook it) is a wedge surface or incline 20 upon which the opposite end ofthe head rides when the handle is at the bottom of the slot. The wedgesurface acts to force the head against the hook and preven rattling ofthe pin. A guard 21 extends downwardly from the housing and overlaps theratchet and in case the pivot at the opposite side of the sash shouldbecome disconnected the ratchet would bind against the guard and preventtl sash from tilting edgcwise.

The operation of the construction shown is as follows: The sash isprovided at each end with a sash pivot and when it is desired to mountthe sash in the frame the handles 16 are raised above the stop lugs 15of the slots let. If the pivot pins then project slightly from the innerends of the barrels, the sash is placed in the window opening with thepins in the guide slots 11 and upward pressure on the sash will causecomplete retraction of the pins and bring them into register with thesockets 10. The handles are then turned downwardly and the inclinationof the slots forces the pins into the sockets. l Vhen the handles reachthe lugs 15 they are sprung past said lugs to the bottom of the slots,thereby locking the pins in the sockets, and preventing removal of thesash until the pivot pins are retracted. When the sash is thus mountedit may be turned on its pivots to closed, open or any intermediatepositions and will be held in its adjusted position by the action of theratchets and ratchet bolts.

l l hile but one specific embodiment of the invention has been hereinshown it will be understood that various details of the construction maybe varied or omitted without departing from the spirit of the invention.
